VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 247,216, dated September 20, 188 1.

. Application filed March 14, 1881, (N0 model.)

To all whom it may concern:

Be it known that we, PAUL SCHNEIDER and HENRY TRENKAMP, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and Improved Vapor-Burner; and we do hereby declare that the following is a full, clear, and complete description thereof.

The vapor burner herein shown and de-' scribed is an improvement on a patent granted to us September 7, 1880. The said improvement relates to the means employed for developing the gasoline vapor, for generating heat, and for protection to the induction gas-current. In the interior of the perforated dome is arranged a cylinder, through which passes a bifurcated feed-pipe, and at right angles thereto and the cylinder, or nearly so, is a gas-pipe, which passes through one side of the dome-cylinder and through the bifurcations of the feedpipe. By this means the gas is rapidly generated in the passage of the gasoline through said burner and its connections, which gas is conveyed, as hereinafter shown, to the interior of the said cylinder, from which it passes into the dome-chamber formed between the cylinder and the interior of the dome. From this chamber the flame issues through the orifices thereof. The gas-pipe is provided with a needlevalve mechanism and a device for arresting the passage of vapor or gas from the needle-valve to the burner and a cup to receive oil for igniting the burner. Attached to the side of the dome is a shield or hood, which extends therefrom and over the sides of the opening of the induction gas-pipe, to protect the gas-currents from being disturbed by wind or otherwise in its direct passage from the needle-valve to the said gas-pipe.

For a more full and complete description of said vapor-burner mechanism and its operation, reference will be had to the following specification and to the annexed drawings, in which- Figure 1 is a side view of the burner. Fig. 2 is a vertical section of the dome and interior parts. Fig. 3 is a transverse horizontal sectionin the direction of the line 00 .00, Fig. 1. Figs. 4, 5, and 6 are detached sections.

Like letters of reference refer in the several views.

In the drawings, A represents the oil-induction pipe, as seen in Fig. 1, which is connected to like We to the bifurcated pipe B, theupper end. of which opens into the chamber 0 of the cap 0, as seen in Fig. 2. From the chamber 0 extendsa vapor or gas pipe, D, which isin open relation and connection with the needle-valve chamber in the pipe E. The needle-valve is provided with a screw-stem, F, and is arranged in the pipe E in the ordinary way, by means of which the vaporized gasoline from the pipe B and chamber O is controlled and directed in its passage to and through the conduit G, Figs. 2 and 3, into the chamber 'H,'fro1n which the vapor passes into the chamber I of the dome J, and

out through the openings to in jets of flame.

Said conduit Gr may be arranged in relation to the burner at any suitable angle and the needle-valve adjusted accordingly.

The chamber H is formed by a cylinder, K, attached to thefloor J of the dome. The upper end of the cylinder opens into the chamber I, as seen in Fig.2, which admits of the vapor passing over the top of the cylinder into the annular chamber I, formed between the cylinder and the interior of the dome. In place of an entire cylinder, a vertical section thereof may be used by being placed in such position within the dome as to direct the entering currents of gas from the conduit Gr to the upper portion of the dome, so that the gas m ay be sul'-' ficiently oxygenated to produce a perfect combustion through the opening of the dome.

It will be seen that the pipe B is bifurcatedthat is, it branches off or curves around, form-' ing two parts, I) 1), between the lower and upper ends, as seen in Figs. 3 and 4, forming an opening, L, Fig. 4, through which passes the induction vapor-pipe G, and thus surrounding it by the parts B and b, as seen in Figs. 3, 4, and 5. By this means the vapor, as it passes from theneedle-valve, is notimpinged against the oilinduction pipe and deflected back or retarded, as in our patent referred to, but is conveyed through and beyond the inductionpipe B into the chamber H without being restrained or deflected from the dome by an intervening pipe, as in our said patent.

The cap 0 is held in place upon the dome by screwing it on the upper end of the pipe B, which is threaded into the floor of the chamber O, as shown at c, Fig. 2, and the pipe Bis held securely in position by the nut M, which screws onto the lower exterior part of the pipe The nut is by means of the screw pressed up against the collar N on the under side of the dome, as seen in Fig. 2, and draws the cap 0 securely down upon the top of the dome. At the same time the pipe G extends through the opening L in pipe B, as before stated. The pipe G is screwed atdin the side of the dome, or it maybe removablyconnected to the burner otherwise.

Directly under the needle-valve is pivoted a drip-cup, 0, Fig.1. The pivotal connection is made by a stem, which extends up from the interior of the cup, and is loosely fitted to an eye or lug, e, projecting from and below the needle-valve tube. Said stem is held in the eye by a pin passing through it above the eye. By this means the cup has a pivotal suspension.

Extending up from the cup is a shield, P. The purpose of the cup is to receive oil from the needle-valve, to be ignited for firing the burner, and theshield P,on being turned around in front of the orifice of pipe Gr, prevents oil from entering therein on opening the needlevalve, but is conducted into the cup 0, for the purpose before stated. As the shield with the cup is pivoted at 0, Fig. 1, the cup may be readily adjusted with the shield, as required.

Attached to the side of the dome, over the pipe G, is a shield or hood, R, as seen in Fig. 6, and indicated by the dotted lines R in Fig. 1. This hood extends out from the dome over the top and on one or both sides of the pipe, whereby the outer end of the pipe is covered on the top and sides by the hood, which may be curved or of an angular shape around the pipe, the purpose of which is to aidin protecting the current of gas from the needle-"alve from being disturbed or turned from the induction-pipe by the wind, draft, or otherwise when exposed to such influences by opening doors, windows, &c. In some cases it may only be needed to have the hood depend upon one side of the pipe to protect the ingress of the current of gas, which materially prevents the usual flickering flame from vapor-burners, caused by the disturbance of the gas in its passage from the needle-valve to the inductionpipe.

In the operation of the burner the oil from the reservoir is admitted to the burner through the induction-pipe A, which is screwed to the lower interior partof the pipe B. ThroughB it passes to the chamber 0, from which the passage to the needle-valve is through the pipe D. In the passage of the oil through the pipe B, chamber 0, and pipe D it becomes vaporized, and is admitted into the pipe Gin a gaseous 0r vaporous state. From the pipe G the vapor passes to the chamber H, and thence over the top of the said chamber-wall into the chamber I, from which it issues in jets of flame through the apertures of the dome for heating purposes. The heat thus developed continues to generate the vapor or gas from the oil in its circuit in the manner before set forth, so long as the flame ofthe burner isconstant and oil supplied.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In vapor-burners, the cylinderKand bifurcated pipe B, both arranged within the perforated dome, in combination with the pipe G, extending through the pipe B from the exterior, and cap 0, with a gas-pipe extending therefrom to the needle-valve mechanism, substantially as described, and for the purpose specified.

2. A vapor-burner consisting of the chamber 0, formed within the cap of the dome, and a bifurcated induction-pipe opening into said chamber, with an eduction-pipe leading therefrom to the needle-valve mechanism, in combination with the annular chamber H, closed at the bottom by the floor of the dome, and Open at the top into the chamber of the dome, substantially as described, and for the purpose specified.

3. The bifurcated pipe B, provided with threaded ends, the upper end screwing into the floor of the chamber 0, and to the lower end a screw-nut, in combination with the perforated dome and cylinder K, constructed and arranged substantially as set forth.

4. In combination with a vapor-burner, a eylindrical partition within the dome, connected with the floor thereof and opening into the interior ofthe dome above, forming double chambers H I, the bifurcated pipe B, attached to cap 0, needle-valve, and drip-cup, arranged substantially as set forth.

In testimony whereofwe atfix our signatures in presence of two witnesses.
